A nagging question still haunts the minds of many Americans. Did Lee
             Harvey Oswald really act alone, as the Warren Commission's report stated,
             or was there a conspiracy, hatched by the Mob, the CIA, the FBI, or some
             other organization, to kill President John F. Kennedy at the height of his
             political power' Perhaps the truth will never be known, and President
             Kennedy's real murderer will never be brought to justice. Several of the
             conspiracy theories refuse to die - here are some of the most popular and
             enduring theories.
             The CIA Theory and Jim Garrison
             New Orleans District Attorney Jim Garrison's theory is probably the
             most well known of the conspiracy theories because it was made into a film
             starring Kevin Costner and directed by Irving Stone. Garrison, through
             several investigative methods, believed a local businessman named Clay Shaw
             was involved in a conspiracy to kill President Kennedy, and that Shaw's
             involvement went as high as the national Central Intelligence Agency (CIA).
             While many historians still believe Garrison's accusations were
             "groundless" (Holland 10), the legend of his prosecution of Shaw lives on,
             and there are still some unanswered questions regarding the theory, even
             though Shaw was eventually found not guilty of any conspiracy or
             wrongdoing.
             Basically, Garrison's theory was that Shaw was a CIA informant, who
             took part in a CIA "coup d'etat" constructed to remove Kennedy from power
             because of ongoing clashes with the CIA and other government agencies, and
             the belief that Kennedy had socialist or communistic leanings. Garrison
             wrote a book about his life and beliefs, called, "On the Trail of the
             Assassins." In that book he wrote, "'What happened at Dealey Plaza in
             Dallas on November 22, 1963, was a coup d'etat. I believe that it was
             instigated and planned long in advance by fanatical anticommunists in the
             United States intelligence community'" (Holland 10). Whi...
